# Upstream only installs a static library. The original antlr ebuild
# built a shared library manually, which isn't so great either. This
# ebuild applies libtool instead and therefore an autoreconf is
# required. A couple of errors concerning tr have been seen but the
# final result still looks good. This also sidesteps bug #554344 plus
# the need to call einstall.
